McConnell said that he's decided to cancel the usual summer getaway "due to the historic obstruction by Senate Democrats of the president's nominees." He also cited his goal of passing the annual appropriations bills before the end of the fiscal year, on Sept. 30.

Not all is lost for senators hoping to take a break. The Republican leader's office says it's expected that senators will be away from Washington during the first full week of August before returning for the rest of the month.
